I'm from Hootsuite. We're a Canadian tech company who provides products
and services to businesses, organizations and individuals to really help
them succeed on social. We have leveraged Go in our stack for the past
4+ years. I am super happy to give back to Go on behalf of Hootsuite
through a small contribution to pkgsite (with a few more in the works).
We love this project and we love open source :)
Hopefully we can give back more in the future!

TestDependencies defines the dependency policy
(what can depend on what) for the standard library.
The standard library has outgrown the idea of writing
the policy as a plain map literal. Also, the checker was
ignoring vendored packages, which makes it miss real
problems.
This commit adds a little language for describing
partial orders and rewrites the policy in that language.
It also changes the checker to look inside vendored
packages and adds those to the policy as well.
This turned up one important problem: net is depending
on fmt, unicode via golang.org/x/net/dns/dnsmessage,
filed as #40070.
This is a test-only change, so it should be appropriate
even for the release freeze, especially since it identified
a real bug.

Summary
The crypto/tls/generate_cert.go utility should only set the template
x509.Certificate's KeyUsage field to a value with the
x509.KeyUsageKeyEncipherment bits set when the certificate subject
public key is an RSA public key, not an ECDSA or ED25519 public key.
Background
RFC 5480 describes the usage of ECDSA elliptic curve subject keys with
X.509. Unfortunately while Section 3 "Key Usages Bits" indicates which
key usage bits MAY be used with a certificate that indicates
id-ecPublicKey in the SubjectPublicKeyInfo field it doesn't provide
guidance on which usages should *not* be included (e.g. the
keyEncipherment bit, which is particular to RSA key exchange). The same
problem is present in RFC 8410 Section 5 describing Key Usage Bits for
ED25519 elliptic curve subject keys.
There's an update to RFC 5480 in last call stage within the IETF LAMPS
WG, draft-ietf-lamps-5480-ku-clarifications-00. This update is meant
to clarify the allowed Key Usages extension values for certificates with
ECDSA subject public keys by adding:
> If the keyUsage extension is present in a certificate that indicates
> id-ecPublicKey as algorithm of AlgorithmIdentifier [RFC2986] in
> SubjectPublicKeyInfo, then following values MUST NOT be present:
>
> keyEncipherment; and
> dataEncipherment.
I don't believe there is an update for RFC 8410 in the works but I
suspect it will be clarified similarly in the future.
This commit updates generate_cert.go to ensure when the certificate
public key is ECDSA or ED25519 the generated certificate has the
x509.Certificate.KeyUsage field set to a value that doesn't include KUs
specific to RSA. For ECDSA keys this will adhere to the updated RFC 5480
language.

When linking against a Go shared library, when a global variable
in the main module has a type defined in the shared library, the
linker needs to pull the GC data from the shared library to build
the GC program for the global variable. Currently, this fails
silently, as the shared library file is closed too early and the
read failed (with no error check), causing a zero GC map emitted
for the variable, which in turn causes the runtime to treat the
variable as pointerless.
For now, fix this by keeping the file open. In the future we may
want to use mmap to read from the shared library instead.
Also add error checking. And fix a (mostly harmless) mistake in
size caluculation.
Also remove an erroneous condition for ARM64. ARM64 used to have
a special case to get the addend from the relocation on the
gcdata field. That was removed, but the new code accidentally
returned 0 unconditionally. It's no longer necessary to have any
special case, since the addend is now applied directly to the
gcdata field on ARM64, like on all the other platforms.

CL 230037 changed cmd/cgo to emit "type _Ctype_foo = bar" aliases for
all C.foo types mentioned in the original Go source files. However,
cmd/cgo already emits an appropriate type definition for _Ctype_void.
So if a source file explicitly mentions C.void, this resulted in
_Ctype_void being declared multiple times.
This CL fixes the issue by suppressing the "type _Ctype_void =
_Ctype_void" alias before printing it. This should be safe because
_Ctype_void is the only type that's specially emitted in out.go at the
moment.
A somewhat better fix might be to fix how _Ctype_void is declared in
the cmd/cgo "frontend", but this is a less invasive fix.
